How many isosceles triangles with integer sides are possible such that sum of two of the side is 12?
Show Hint
When dealing with triangle sides, always enforce the Triangle Inequality Theorem
(\(a+b > c\), \(b+c > a\), \(c+a > b\)).
For isosceles triangles, remember to split into two distinct cases: the sum involves the two identical sides, or the sum involves one identical side and the base.
